“I probably shouldn’t do this again,” Joaquin Phoenix confessed, his voice carrying the weight of both triumph and caution. That’s how the Academy Award-winning actor described his grueling 52-pound weight loss for his role as Arthur Fleck in Joker. But what drives someone to push their body to such extremes? And was it all worth it?
Let’s take a closer look at Joaquin Phoenix’s Joker weight loss journey—a transformation that was as haunting as the character he portrayed.
Before stepping into the skin of Arthur Fleck, Phoenix was at a comfortable weight. But as the script called for a man unraveling into madness, Phoenix knew his physical appearance had to mirror that descent.
“The first thing for us was the weight loss,” Phoenix told Esquire. The actor dropped from around 180 pounds to a startling 128 pounds. That’s 52 pounds—gone. The result? A body so gaunt and fragile, it almost felt like watching a walking skeleton on screen.
“It wasn’t just about looking thin,” Phoenix later shared in an interview with Rolling Stone. “It was about feeling the desperation, the hunger, the isolation.” But achieving that look came at a steep price.
How did Phoenix manage such a dramatic weight loss?
The answer is almost as unsettling as the character himself. “I lived on lettuce, steamed vegetables, and apples,” Phoenix admitted during a press event for Joker: Folie à Deux. At one point, rumors swirled that he ate just one apple a day—a claim Phoenix later neither confirmed nor denied.
But he did acknowledge how dangerous this approach was. “I was supervised by a doctor,” Phoenix noted, “but even with that, I don’t recommend it.” His daily routine was stripped to its bare essentials, with calories meticulously counted and exercise limited to light activities, ensuring he didn’t burn out completely.
And yet, even with medical supervision, the process took a toll.
Losing weight at this rate isn’t just a physical battle—it’s a mental one too. Phoenix opened up about the emotional strain that came with his transformation.
“There’s something about losing that much weight that affects your psychology,” Phoenix told USA Today. “You start to go mad.” The actor described feeling isolated and obsessive, often retreating into his own thoughts. Even simple tasks felt monumental.
The transformation was so intense that Phoenix admitted, “I probably shouldn’t do this again.” But for Joker, the sacrifice paid off. His performance earned him the Oscar for Best Actor, cementing his place in cinematic history.
When it came time to reprise his role for Joker: Folie à Deux, fans wondered—would Phoenix put his body through the wringer once more?
“It was a bit more complicated this time,” Phoenix revealed in an interview with Variety. Though he did lose weight again, he confessed that he approached the process with more caution. “I realized the toll it took on me the first time. I probably shouldn’t do it again.”
Phoenix wasn’t alone in his struggles. Lady Gaga, who stars alongside him in the sequel, also undertook a punishing diet. “We both knew what we were getting into,” Phoenix said, hinting at the shared hardships of embodying such dark, twisted characters.
When Joker hit theaters, fans were shocked by Phoenix’s appearance. Social media buzzed with comments about his “upsettingly thin” frame, and many worried about the lengths actors go for roles.
“Can we just appreciate how Joaquin Phoenix went on an extremely dangerous diet for this role?” one Reddit user wrote. Others debated whether such transformations should be celebrated or criticized.
But despite the concern, there’s no denying that Phoenix’s dedication paid off. His portrayal of Arthur Fleck was both chilling and captivating—a performance that wouldn’t have been the same without his drastic physical transformation.
Joaquin Phoenix’s 52-pound weight loss for Joker is more than just a headline—it’s a testament to the extremes actors will go for their craft. But it also serves as a cautionary tale.
“I don’t think it’s something I’d ever want to repeat,” Phoenix admitted. And after seeing the toll it took, most fans would agree.
Yet, despite the risks, Phoenix’s transformation remains one of the most talked-about in cinematic history. It’s a stark reminder that sometimes, the line between dedication and danger is razor-thin.
